Gentlemen:

Reference is hereby made to that certain letter agreement dated as of even date
hereof between you, R2 Investments and Q Opportunity Fund (collectively, the "Q
Investors") and Globalstar Telecommunications Limited (the "GTL Letter").
Capitalized terms used herein not otherwise defined will have the meanings set
forth in the GTL Letter.

You hereby agree to, and agree to cause the other Q Investors to, transfer and
convey to us, immediately following issuance of the Dividend Make-Whole Payment
by GTL to the Q Investors pursuant to the GTL Letter, an aggregate of 64,906
shares of Common Stock, free and clear of all liens.

In consideration for such transfer and delivery of the shares of Common Stock to
us as set forth above, we hereby covenant and agree that, if the aggregate gross
proceeds to the Q Investors from the sale of the 516,505 Remaining Make-Whole
Shares (as defined below), less the amount of the sale concessions of up to 6
cents per share paid by the Q Investors to Bear, Stearns & Co. Inc. in
connection therewith (such difference, the "Actual Sale Amount"), are less than
$13,429,140 (the "Guaranteed Amount"), we will, as promptly as practicable
following our receipt of a Shortfall Notice as set forth below, but in any event
no later than three business days thereafter, deliver to you the difference (the
"Loral Payment Amount") between the Guaranteed Amount and the Actual Sale Amount
in immediately available funds to your account as set forth in the Shortfall
Notice. "Remaining Make-Whole Shares" will equal the difference between the
number of shares issued to the Q Investors as the Dividend Make-Whole Payment
under the GTL Letter and 64,906 shares.

If the Actual Sale Amount shall be greater than the Guaranteed Amount, you will
deliver to us the difference in immediately available funds to an account
designated by us to you, such payment to be made on the settlement date for the
last sale transaction relating to the Remaining Make-Whole Shares.

You hereby agree that you will, and will cause the other Q Investors to, sell
all and not less than all of the Remaining Make-Whole Shares through Bear,
Stearns & Co. Inc. during the period ending on December 10, 1999, unless
extended by us. You further agree that you will use your, and will cause the
other Q Investors to use their, reasonable
   2
best efforts to cause Bear, Stearns & Co. Inc. to obtain the most favorable
price for the Remaining Make-Whole Shares in connection with such sale
transactions. Within 24 hours from the date the last sale transaction relating
to the Remaining Make-Whole Shares is entered into, you will deliver to us
either (x) if the Actual Sale Amount is less than the Guaranteed Amount, a
written notice (the "Shortfall Notice") which will provide for the following:
(i) a certification by you that all conditions to the sales of the Remaining
Make-Whole Shares set forth in this paragraph have been complied with; (ii) the
Actual Sale Amount attaching thereto evidence of each sale transaction relating
to the Remaining Make-Whole Shares entered into by you and the other Q Investors
and the gross proceeds derived therefrom and the selling concessions paid in
connection therewith; and (iii) wire transfer instructions relating to the Loral
Payment Amount or (y) if the Actual Sale Amount is equal to or greater than the
Guaranteed Amount, a certification (the "Certification") of the Actual Sale
Amount attaching thereto evidence of each sale transaction relating to the
Remaining Make-Whole Shares entered into by you and the other Q Investors and
the gross proceeds derived therefrom and the selling concessions paid in
connection therewith. You will deliver the Shortfall Notice or Certification to
us at the following address:

to cause the other Q Investors to take the actions, and to take action on behalf
of the other Q Investors, as contemplated herein.
